SPECIFICATION forming part of Letters Patent No. 447,572, dated March 3, 1891.

Application filed May 31, 1890. Serial No. 353,817. (No model.)

To all whom it may concern.-

Be it known that I, ALFRED LISTER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Privy-Vaults; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to prevent the ingress of solid matter to the pipes leading from a privy-vault to the sewer or cesspool and the clogging and stopping of the pipes resulting therefrom, and thereby improving the Sanitary condition of the vaults. The invention consists in the improved privy-vault and in the arrangement and combination of the several parts thereof, as herein set forth, and finally pointed out in the claims.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts where they occur, Figure 1 represents a central vertical section through a privy and its vault embodying my improvements. Fig. 2 is a plan view of a certain grated and removable partition used in connection therewith, and Fig. 3 is a transverse section taken through line a: of said Fig. 2.

In said drawings, A indicates a series of privies. B indicatesavault built thereunder, and 0 indicates an extension or sub-vault, which is separate from the main vault B by a partition (Z and receives the overflow therefrom through an opening or perforation in said partition, as will be understood. Said sub-=vault is connected with a sewer or cesspool by an escape or drain pipe f, the mouth of or entrance to which is or may be covered by a perforated cap g, Fig. 1, and is provided with one or more grated partitions, in the present instance two a and c, which extend diagonally from the bottom to the rear wall, as indicated in said Fig. l. Said partitions are similar to one another, except that the lower one e when it is used is smaller and the bars are closer together, and I prefer to make them by arranging straight rods 2' t parallel with each other and securing their ends in the two end pieces jj. This gives a free and uninterrupted passage for the fluid and also permits of the solid substance being easily moved up on the rods to prevent its 0bstructing the passage of the fluid or thinner portion. Said partitions serve to effectually hold and prevent any solid or objectionable matter from getting into and clogging the drain-pipe, and thereby saves the heavy expense and trouble of cleaning or freeing said pipes, as is frequently the case.

By placing the grates diagonally in the sub- Vault with their lower ends nearest to the inlet the water or liquid portion in passing through them will wash or force the larger particles of the solid portion up the inclined bars or surface of the grates, and thus keep the lower portion of the grates open or free for the passage of the liquid portions. This arrangement of the grates is best accomplished by placing the inlet and outlet upon opposite sides of the vault and at or near the bottom, and then placing the grates between them with their lower ends nearest the inlet and having their opposite ends over or above the outlet.

Should the grated partitions become clogged at any time from the accumulation of solid matter thereon, they can easily be freed therefrom by means of a hoe or scraper by opening or removing the lid it without removing the grates, as will be manifest, although said grates, as will be seen, may be lifted out at pleasure, if found necessary or desirable to do so. The object of the lower and finer grated partition and of the perforated cap is to catch and hold any objectionable matter which might by any possibility pass through the larger partition and prevent it from getting into the drain-pipe. Said lid it may be hinged or otherwise held in position upon the vault, as may be preferred.

It will be manifest in cases where the construction or use of the extension of sub-vault is impracticable that the grated or perforated partition or partitions e and (3 can and may be adjusted in the same manner and with similar results across the ordinary vault.

Having thus described my invention, what I claim as new is 1. In a privy-vault, the combination, with a vertically-arranged partition having an openingat its bottom, of an inclined perforated partition extending from the opening in the vertical partition diagonally upward to and resting upon the opposite side of the vault over the outlet, substantially as described.

2. In a privy-vault, the combination, with a Vertically-arranged partition having an opening at its bottom, of a partition extending diagonally upward from the opening in the vertical partition to and resting against the opposite wall of the vanltover the outlet, said partition consisting of a series of straight rods arranged parallel with each other and having their ends secured in end pieces, substantially as described.

In testimony that'I claim the foregoing I have hereunto set my hand this 99th day oi.- May, 1890.

ALFRED LISTER.
